According to the present invention, in the device for initiating the winding operation in windposition.

In the accompanying drawings two embodiments of the device according to the invention are illustrated by way of example only, in which Fig. 1 shows a side elevation of a first embodiment shortly after the beginning of a new wind- 1 1%;

is connected. This supporting carriage frame la, 2 is mounted, by means of its hollow spindle 2, on a stationarily longitudinally and i" projectin from theplate in the plane thereof, the fo m arm entering. between two guide rails 5 1 2) so that the supporting carriage frame is a stationary stop I I I The winding thread thassesin inthe hollow spindle H by means of roller bearings. The thread feeler 5 section on the line XX-X'X in member 16, which is rockably mounted by means of its carrier spindle I8 against spring action, can

At the beginning of the said be rocked by contact with the winding I5, thereby each time initiating the feed movement of the supporting frame one step with the aid of the means shown by way of example in Figs. 18 and 20. This means comprises, in the present instance, a contact arm I8 secured to the end of the spindle I8 remote from the feeler member I6 for cooperation with two contact blades 28 each of which is connected to one of the leads 29 of an electric motor 30. Thus, when the feeler member I6 is rocked against its loading spring 40,

- the arm I8 bears against the two contact blades 28, thereby closing a ,circuit through the motor 30 for operating the same. The running motor turns, through-the intermediary of a gearing 32, a revolubly mounted screw spindle 33 disengageably intermeshing with a screw threaded clutch member 34. In this way the supporting carriage frame is moved towards the motor, until the contact arm I8 recedes from the contact blades again by action of the feeler member and the motor circuit is thereby broken. The motor is thus stopped and the supporting frame, after having completed a feed step, is set at rest.

when the winding I5 has attained the desired length, the face plate I passes with its arm I beyond the respective end of the guide rails 4, 5, as shown in Fig. 3. At this time, the supporting frame is rocked, advantageously automatically, about its carrier spindle H for half a revolution in the direction of the arrow shown in Fig. 4.

This rocking movement of the supporting frame,

which is then no longer guided by the rails 4, 5, is initiated by the turning belt 3| imparting a driving impulse to this frame by the tension and driving traction of the belt. Incidental thereto the clutch member 34 is moved out of mesh with the screw spindle 33, so that a tension spring anchored at its ends to the machine frame and a non-revoluble arm 36 of the supporting frame respectively becomes operative to return the latter into initial position. During the initial stage of this return movement dogs 31 on the hub of plate Ia engage with mating dogs 31 on the sleeve 2. As the supporting frame returns bringing with it sleeve 2, the latter is simultaneously rocked through by reason of the engagement of its helically curved slot 38 and a guide roller 38 mounted on the stationary hollow shaft I1, all as more explicitly explained in my cognate application Ser. No. 115,419, filed of even date herewith.

During this rocking movement the winding spindle 6 is bodily rocked away from the winding position with the completed cop I5 mounted thereon and in its place the winding spindle 6 carrying the empty winding spool or cop tube 8' is placed into winding position and this spindle is automatically engaged with the driving belt 3| and, consequently, is turned. I

Th'e rocking movement of the supporting frame is limited by the arm I" of the face plate I hitting the guide rail 5. During the supporting member being thereupon again fed by steps, the arm I" of the face plate I arrives at the guide rail 4, so that from there on it enters between the two guide rails 4 and 5, as indicated in Fig. 6, and is thus locked against further rocking in either direction in the new position of adjustment. turning movement of the supporting carriage frame the winding thread 9 is retracted from the respective side of the thread deflector I4 by the gyrating cop I5,

direction of arrow 11 in Fig.

as shown in Fig. 4, and is thereby temporarily moved out of the path of this deflector.

During the longitudinal displacement of the supporting. frame into its initial position, in the 5, the face plate I of the carriage frame hits the thread guide II, which is then rocked away from its stop I3, this being permitted by yielding of the torsion spring I2, so as to change its relative position to the reciprocating thread deflector I4. 'I'hereupon, the winding thread 9 is contacted against the opposite side of the thread deflector I4, as shown in Fig. 5. The winding thread 9, which during the said displacement of the supporting frame (in the direction of arrow 11 in Fig. 5) is wound about the windings present on the cop tube 5 in widely spaced convolutions, is then moved by the thread deflector I4 into the path of a thread catch I9 arranged on the head I of the winding spindle 6, as evident from Fig. 5. The supporting head I of the win 'ng spindle 6 is also provided with the same kind of thread ciitch II which is composed of a spring arm secured at one of its ends to the respective spindle head with a point of its free length on the spindle head,

' thereby exerting a clamping effect at 2| (Fig. 11).

At the point of clamping 2| the thread is held to the thread catch IQ of the spindle head 'I' in loop-shape, as shown in Fig. 8.

Then, as evident from Fig. 9, torn apart due to tension action on its length between the spindle heads I and I, that is, between the wound and the empty cop tubes I and 8 respectively in which way the connection in tween the winding on the cop tube 5 and the spindle head I is interrupted. After the wind-v ing thread has been caught by thethread catch I9 of the spindle head I in the manner shown in Fig. 6, it is retracted laterally from the respective side of the thread deflector I4 in the corresponding-direction by the spindle head I turning about its own axis. Thereupon, the winding thread passes thread deflector I4 again, and the thread guide III assumes the position as shown in Figs. 7 w 9. The winding thread is then shifted inwardly on said guide the more the thread, due to the spindle head I turning, approaches the cop tube 8', and is then wound on the cop tube.-

In this position of reassumed its initial condition order to wind the thread in a cop onto the empty tube 8' in the manner previously explained. During this winding operation the completed wound cop is dotted from the winding of operation in the thread is to the other side of the I 50 the parts, the device has head I and replaced by an empty cop tube. This empty tube is moved into the position of winding automatically, on the winding carried by the cop tube 8 being completed, by means of the movements taking place again in the manner. previously explained, while the completely wound. cop is moved away from the winding position in a gyrating movement.
